Inventor: SAKANO SHINJI
IPC: H04B10/25
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent burning of an optical fiber and end surface fusion in an output end surface when an optical amplifier with a high power of 20dBm or above is used. SOLUTION: A mode field 11 of an output end part of a single mode optical fiber emitting high power light is spread, and light power density is lowered. Further, the substance with thermal conductivity and a melting point temp. higher than the main body of the optical fiber is coated on the end surface 5. A film thickness of a coating film is set in a wavelength that a phase is shifted by 1/4 wave length in the wavelength of light. Further, the similar fiber is used also for the optical fiber of the other party to be coupled. Since the end surface fusion of the optical fiber doesn't occur when a high power light output is dealt with reliability of a device and a light transmission system are enhanced, and the cost is reduced.
